Abstract: When receiving a first data frame sent by a transmitting apparatus, a receiving apparatus may return error indication information including an identifier of at least one erroneous codeword group to the transmitting apparatus if it is found that an error occurs in an initial codeword of the first data frame. The transmitting apparatus may obtain the erroneous codeword group and encode the erroneous codeword group, and retransmit a part of a sub check codeword obtained through encoding to the receiving apparatus. The receiving apparatus may obtain a third check matrix based on a first check matrix, a second check matrix, and a location of the at least one erroneous codeword group in the initial codeword, and re-decode the retransmitted partial sub check codeword and content of the first data frame together based on the third check matrix, so as to obtain a correct initial codeword.

Abstract: An optical fiber plug includes a plug body, a locking structure, and an unlocking structure. The locking structure is located on a side wall of the plug body, and configured to, when the plug body is inserted into an optical fiber adapter in an insertion direction, match an elastic bolt of the optical fiber adapter, to lock a relative position between the plug body and the optical fiber adapter. The unlocking structure is located on the side wall of the plug body, and configured to, when the plug body is detached from the optical fiber adapter in a direction opposite to the insertion direction, release matching between the locking structure and the elastic bolt. By using the optical fiber plug, a problem related to complexity of mounting and removal is resolved and a space is for operation can be reduced.
